Hi.
I dont have the time to write a full code answer (and test it for you) for you but the simple answer is as such. yes this is possible.
Excel.xsl uses XSL language specification. The for-each tag that is iterating to build the CELLS, so just exclude the ID in the loop. Now i didn't test this code but just wrote it freehand but it should lead you down the correct path to solve your problem.
